为了探讨塑料-NaI（T1）复合探测器对点状γ射线源的探测效率与晶体尺寸之间的关系,利用蒙特卡罗方法及相关软件,在VC＋＋开发平台下编制了可以自定义塑料-NaI（T1）复合晶体尺寸的软件,实现对不同能量的γ射线的探测效率的计算.根据计算得到的数据矩阵拟合出不同尺寸探测器对点源的效率函数,并确定出函数的参数.

In order to study the relationship between the counting efficiency and crystal size,based on Monte Carlo and related software,in the development platform of the VC＋＋,this paper prepared to customize the plastic-NaI（T1） crystal size of the software complex,for implementation of different energy γ-ray detection efficiency of the calculation.According to calculation of the data matrix,it fit a different size detector efficiency function of poi...
